[0001] The present invention relates to the technical field of shot blasting machines, and particularly to a dust removal and purification device for a shot blasting machine. Background Art

[0002] As an important device for metal surface treatment, shot blasting machines are widely used in manufacturing industries such as steel structures, automobiles, and ships. However, during the shot blasting operation, a large amount of dust and waste are generated. These dusts not only affect the working environment but may also pose hazards to the health of workers. At the same time, there are also problems with non-compliance with environmental protection standards.

[0003] After retrieval, a Chinese patent with the publication number CN118874076A discloses a dust removal device for a shot blasting machine, which includes a mounting frame. A dust suction cylinder is installed on the top of the mounting frame. An air inlet pipe is installed at one end of the dust suction cylinder. A ventilation plate is rotatably connected inside the air inlet pipe. The ventilation plate includes a second rotating shaft, and the second rotating shaft is rotatably connected to the air inlet pipe and is provided with an adjusting plate. The adjusting plate is hinged to the output end of a first electric cylinder, and the first electric cylinder is hinged to the side wall of the air inlet pipe. A filter plate matching the air inlet pipe is installed inside the dust suction cylinder. An installation cylinder is installed at the end of the dust suction cylinder away from the air inlet pipe. A motor is installed inside the installation cylinder, and a fan blade is installed at the output end of the motor. A dust outlet hole is provided at the bottom of the dust suction cylinder. Therefore, the invention realizes the adjustment of the air volume through the cooperation of the ventilation plate and the second electric cylinder, and further realizes the adjustment of the dust suction force, improving the dust suction efficiency.

[0004] In the above-mentioned prior art solution, a filter plate is used to filter the air containing dust, so that the filter plate intercepts the dust. The filter plate is placed obliquely to reduce the probability of blockage of the filter plate. However, during actual use, when the motor works to pump out the air inside the dust suction cylinder, the inside of the dust suction cylinder is in a negative pressure state, and the motor and the fan blade are arranged at a position close to the top. Therefore, the dust will adhere to the side wall of the filter plate under the influence of the negative pressure, still blocking the side wall of the filter plate, and the filter plate needs to be cleaned frequently.

[0035] In some embodiments, support columns are fixedly installed on the bottom wall surface of the converging box.

[0036] Compared with the prior art, the remarkable advantages of the present invention are as follows:

[0037] First: In the present invention, the dust deposited inside the collection box is guided by the gathering box, facilitating the dust to fall into the inside of the conveying pipe. Through the rotation of the output shaft of the driving motor, the auger rod is driven to rotate. The water and dust inside the collection box are conveyed together into the inside of the drain pipe by the auger rod. The spiral blades on the side wall of the auger rod are distributed more densely towards the end closer to the drain pipe. Therefore, the distance between the spiral blades on the auger rod becomes smaller and the space also shrinks accordingly. The dust and water conveyed by the auger rod are squeezed. By fixedly installing a drainage box on the outer side wall of the drain pipe, the water filtering ring inside the drainage box separates the dust inside the drain pipe, while the water seeps through the water filtering ring and remains inside the drainage box. Through the operation of the return water pump, the water is returned to the inside of the collection box through the return pipe and the water inlet pipe, enabling the water to be reused. The dust remaining inside the drain pipe forms lumps under the extrusion of the auger rod and is input into the inside of the collection cover as the auger rod rotates, enabling the collection cover to collect the dust. By fusing the dust with water, the dust is separated from the air. When the dust settles, through the cooperation of the auger rod and the water filtering ring inside the drainage box, the dust is separated from the water, completing the cleaning of the dust; this solves the problem that the existing dust removal and purification device needs to frequently clean the filter plate.

[0038] Second: In the present invention, by fitting the side wall of the linkage plate to the side wall of the auger rod, when the auger rod rotates, it will push the linkage plate, the connecting strip, and the spoiler strip to move synchronously. Under the elastic influence of the return spring, when the return spring will push the positioning strip to return to its original position, it is convenient for the linkage plate, the connecting strip, and the spoiler strip to return to their original positions, facilitating the repeated swinging of the spoiler strip. The spoiler strip at the top of the positioning strip also swings back and forth. The spoiler cloth fixedly installed on the inner side wall of the spoiler strip contacts the water as the spoiler strip moves, increasing the contact area between the spoiler strip and the water. By disturbing the water at the bottom end of the air inlet pipe of the spoiler strip to be in a stable state, it is convenient for the dust in the water to settle.

[0039] Third: In the present invention, since the crushing net is rotatably installed at the bottom end of the side wall of the air inlet pipe, through the mutual cooperation of the connecting column and the linkage rod, when the spoiler strip swings back and forth, the crushing net will rotate a certain angle in different directions repeatedly. Since the crushing net is in a mesh shape and is located at the bottom end of the side wall of the air inlet pipe, when bubbles are generated in the water, the bubbles will surely contact the side wall of the crushing net when floating upward. The crushing net pierces the bubbles, enabling the dust in the air to fully contact the water and improving the air purification effect.

[0040] Fourth: In the present invention, the crushing net will rotate repeatedly under the cooperation of the connecting column and the linkage rod, and the swinging ball will swing under the influence of centrifugal force, hitting the bottom end of the inner wall of the collection box, causing the inner wall of the collection box to vibrate. The vibration of the side wall of the collection box will be transmitted to the side wall of the gathering box, causing the dust deposited on the side wall of the gathering box to flow into the interior of the conveying pipe more quickly with the vibration, improving the dust treatment speed.

[0041] Fifth: In the present invention, by utilizing the elasticity of the support spring to pull the sealing gasket upward, the sealing gasket seals the bottom end of the air inlet pipe. Since the air containing dust is continuously fed into the interior of the air inlet pipe, the air pressure inside the air inlet pipe will become higher and higher until it pushes the sealing gasket downward, creating a gap between the sealing gasket and the air inlet pipe. The air containing dust contacts the water inside the collection box through the gap. After the air pressure inside the collection box is released, the support spring pulls the sealing gasket upward to seal the bottom end of the air inlet pipe. This process repeats, preventing the water inside the collection box from flowing back into the interior of the air inlet pipe. BRIEF DESCRIPTION OF THE DRAWINGS

The air inlet assembly includes a top cover 21, an air inlet pipe 22, an exhaust filter plate 23, and a water inlet pipe 24. The top cover 21 is fixedly installed at the top end of the inner side wall of the collection box 1 by threads. The air inlet pipe 22 is fixedly installed in the middle of the top wall surface of the top cover 21. There are multiple exhaust filter plates 23, and the multiple exhaust filter plates 23 are circumferentially and equidistantly distributed on the top wall surface of the top cover 21. The water inlet pipe 24 is fixedly installed on the side wall of the collection box 1. It is convenient to inject water into the interior of the collection box 1 through the water inlet pipe 24, and to convey the air containing dust into the interior of the collection box 1 through the air inlet pipe 22, and to make the air containing dust discharged at the bottom of the collection box 1 as much as possible, which is convenient for the air to fully contact the water inside the collection box 1. The air discharged outward is filtered through the exhaust filter plate 23 to remove the moisture in the air and reduce the humidity of the discharged air. It is convenient to add water for dust removal into the interior of the collection box 1 through the water inlet pipe 24. A dust removal assembly is provided at the bottom of the collection box 1. The dust removal assembly includes an aggregation box 31, a conveying pipe 32, a drain pipe 33, a collection cover 34, a driving motor 35, a screw rod 36, a drainage box 37, a return water pump 38, and a return pipe 39. The aggregation box 31 is fixedly installed on the bottom wall surface of the collection box 1, and the bottom end of the aggregation box 31 is inclined towards the center. The conveying pipe 32 is fixedly installed on the bottom wall surface of the aggregation box 31, and the cross-section of the conveying pipe 32 is semi-circular. The drain pipe 33 is fixedly installed on the outer side walls of the aggregation box 31 and the conveying pipe 32, and the interior of the drain pipe 33 is communicated with the interior of the conveying pipe 32. The collection cover 34 is threadedly installed on the inner side wall of the drain pipe 33, and the interior of the collection cover 34 is hollow. The driving motor 35 is fixedly installed on the side wall of the drain pipe 33 away from the collection cover 34. The screw rod 36 is arranged inside the conveying pipe 32 and the drain pipe 33, and the spiral blades on the side wall of the screw rod 36 are more densely distributed towards the end closer to the drain pipe 33. The side wall of the screw rod 36 is in contact with the inner side walls of the conveying pipe 32 and the drain pipe 33. The drainage box 37 is fixedly installed on the outer side wall of the drain pipe 33, and a water filtering ring is provided on the inner side wall of the drainage box 37. The return water pump 38 is fixedly installed at the bottom end of the side wall of the drainage box 37. The input end of the return water pump 38 is communicated with the interior of the drainage box 37. The return pipe 39 is fixedly installed on the output shaft of the return water pump 38, and the top end of the return pipe 39 is fixedly installed on the side wall of the water inlet pipe 24;The dust precipitated inside the collection box 1 is guided by the gathering box 31 to facilitate the dust to fall into the inside of the conveying pipe 32. By the rotation of the output shaft of the driving motor 35, the auger rod 36 is driven to rotate. The water and dust inside the collection box 1 are conveyed into the inside of the drain pipe 33 together by the auger rod 36. The spiral blades on the side wall of the auger rod 36 are distributed more densely at the end closer to the drain pipe 33. Therefore, the distance between the spiral blades on the auger rod 36 becomes smaller and the space also shrinks accordingly. The dust and water conveyed by the auger rod 36 are squeezed. By fixedly installing a drainage box 37 on the outer side wall of the drain pipe 33, the water filtering ring inside the drainage box 37 separates the dust inside the drain pipe 33, while the water seeps through the water filtering ring and remains inside the drainage box 37. By the operation of the return water pump 38, the water is returned to the inside of the collection box 1 through the return pipe 39 and the water inlet pipe 24, enabling the water to be reused. The dust remaining inside the drain pipe 33 is formed into lumps by the extrusion of the auger rod 36 and is input into the inside of the collection cover 34 along with the rotation of the auger rod 36, enabling the collection cover 34 to collect the dust. At the same time, the inside of the collection cover 34 is sealed by the collection cover 34 to prevent part of the water from leaking out through the gap between the auger rod 36 and the drain pipe 33, resulting in waste of water resources.;

[0055] Such as Figures 1 - 6As shown, in one embodiment, in order to facilitate the precipitation of dust in water, a flow disturbing component is arranged inside the gathering box 31. The flow disturbing component includes a positioning strip 41, a linkage plate 43, a connecting strip 44, a return spring 45 and a flow disturbing strip 46. The positioning strip 41 is fixedly installed on the inner side wall of the gathering box 31. The bottom wall surface of the positioning strip 41 is attached to the top end side wall of the auger rod 36. A positioning groove 42 is formed on the top wall surface of the positioning strip 41, and the positioning groove 42 penetrates through the bottom wall surface of the positioning strip 41. There are multiple linkage plates 43, and multiple linkage plates 43 are all slidably installed inside the positioning groove 42, and the side walls of multiple linkage plates 43 are respectively attached to the side walls of adjacent blades on the auger rod 36. The connecting strip 44 is fixedly installed on the top wall surfaces of multiple linkage plates 43. The two ends of the return spring 45 are respectively fixedly installed on the connecting strip 44 and the adjacent side inside the gathering box 31. There are multiple flow disturbing strips 46, and multiple flow disturbing strips 46 are fixedly installed on the side wall of the connecting strip 44, and multiple flow disturbing strips 46 are distributed perpendicular to the connecting strip 44. Flow disturbing cloths are fixedly installed on the inner side walls of multiple flow disturbing strips 46; by attaching the side wall of the linkage plate 43 to the side wall of the auger rod 36, when the auger rod 36 rotates, it will push the linkage plate 43, the connecting strip 44 and the flow disturbing strip 46 to move synchronously. Under the elastic influence of the return spring 45, when the return spring 45 will push the positioning strip 41 to return to its original position, it is convenient for the linkage plate 43, the connecting strip 44 and the flow disturbing strip 46 to return to their original positions, and it is convenient for the flow disturbing strip 46 to swing back and forth. The flow disturbing strip 46 at the top of the positioning strip 41 also swings back and forth. The flow disturbing cloth fixedly installed on the inner side wall of the flow disturbing strip 46 contacts the water as the flow disturbing strip 46 moves, increasing the contact area between the flow disturbing strip 46 and the water. By disturbing the water at the bottom end of the air inlet pipe 22 by the flow disturbing strip 46 to keep the water in a stable state, it is convenient for the dust in the water to precipitate.

[0056] As Figures 1 - 7As shown, in one embodiment, in order to avoid the problem that air forms bubbles in water, resulting in incomplete dust treatment, a crushing assembly is provided inside the collection box 1. The crushing assembly includes a crushing net 51, connecting columns 52, linkage rods 53, positioning ropes 54, and swinging balls 55. The crushing net 51 is rotatably installed at the bottom end of the side wall of the exhaust filter plate 23. There are multiple connecting columns 52, and multiple connecting columns 52 are divided into multiple groups in pairs of two. The two ends of each pair of connecting columns 52 are respectively fixedly installed on the top wall surface of the spoiler strip 46 and the bottom wall surface of the crushing net 51. The linkage rod 53 at the bottom of the crushing net 51 is in an eccentric position. There are multiple linkage rods 53, and the two ends of multiple linkage rods 53 are respectively rotatably installed on the side walls of two adjacent connecting columns 52. Since the crushing net 51 is rotatably installed at the bottom end of the side wall of the intake pipe 22, through the mutual cooperation of the connecting columns 52 and the linkage rods 53, when the spoiler strip 46 swings back and forth, the crushing net 51 will repeatedly rotate a certain angle in different directions. Since the crushing net 51 is in a mesh shape and the crushing net 51 is located at the bottom end of the side wall of the intake pipe 22, when bubbles are generated in the water, the bubbles will surely contact the side wall of the crushing net 51 when floating upward. The crushing net 51 pierces the bubbles, enabling the dust in the air to fully contact the water and improving the air purification effect. There are multiple positioning ropes 54 and swinging balls 55. Multiple positioning ropes 54 are fixedly installed on the bottom wall surface of the crushing net 51 at equal circumferential intervals, and multiple swinging balls 55 are respectively fixedly installed at the bottom ends of multiple positioning ropes 54. The crushing net 51 will rotate repeatedly under the cooperation of the connecting columns 52 and the linkage rods 53, and the swinging balls 55 will swing under the influence of centrifugal force and hit the bottom end of the inner wall of the collection box 1, causing the inner wall of the collection box 1 to vibrate. The vibration of the side wall of the collection box 1 will be transmitted to the side wall of the gathering box 31, causing the dust deposited on the side wall of the gathering box 31 to flow into the inside of the conveying pipe 32 at an accelerated speed along with the vibration, improving the dust treatment speed.

[0057] As Figure 2 and Figure 7As shown, in one embodiment, in order to prevent the water inside the collection box 1 from flowing back into the interior of the intake pipe 22, a sealing assembly is provided inside the intake pipe 22. The sealing assembly includes a fixed rod 61, a sliding rod 62, a sealing gasket 63, and a support spring 64. The fixed rod 61 is fixedly installed on the inner sidewall of the intake pipe 22. The sliding rod 62 slidably penetrates the sidewall of the fixed rod 61. The sealing gasket 63 is located at the bottom of the intake pipe 22. The sidewall of the sliding rod 62 close to the sealing gasket 63 is fixedly connected. The support spring 64 is sleeved on the sidewall of the sliding rod 62. The two ends of the support spring 64 are respectively fixedly connected to the sidewall of the fixed rod 61 and the sidewall close to the support spring 64. By utilizing the elasticity of the support spring 64 to pull the sealing gasket 63 upward, the sealing gasket 63 seals the bottom end of the intake pipe 22. Since the air containing dust is continuously fed into the interior of the intake pipe 22, the air pressure inside the intake pipe 22 will become higher and higher until it pushes the sealing gasket 63 downward, creating a gap between the sealing gasket 63 and the intake pipe 22. The air containing dust contacts the water inside the collection box 1 through the gap. After the air pressure inside the collection box 1 is released, the support spring 64 pulls the sealing gasket 63 upward to seal the bottom end of the intake pipe 22. This process repeats to prevent the water inside the collection box 1 from flowing back into the interior of the intake pipe 22.

[0058] As Figure 1 shown, in one embodiment, in order to ensure the stable position of the collection box 1, support columns 7 are fixedly installed on the bottom wall surface of the gathering box 31; the device is supported by the support columns 7 to ensure the stable position of the device.

[0059] The specific working method is as follows: The gathering box 31 guides the dust deposited inside the collection box 1 to facilitate the dust to fall into the interior of the conveying pipe 32. By the rotation of the output shaft of the driving motor 35, the auger rod 36 is driven to rotate. The auger rod 36 conveys the water and dust inside the collection box 1 together into the interior of the drain pipe 33. The spiral blades on the sidewall of the auger rod 36 are distributed more densely towards the end closer to the drain pipe 33. Therefore, the distance between the spiral blades on the auger rod 36 becomes smaller and the space also shrinks. The dust and water conveyed by the auger rod 36 are squeezed. By fixedly installing a drainage box 37 on the outer sidewall of the drain pipe 33, the water filtering ring inside the drainage box 37 separates the dust inside the drain pipe 33, while the water seeps through the water filtering ring and remains inside the drainage box 37. Through the operation of the return water pump 38, the water is returned to the interior of the collection box 1 through the return pipe 39 and the intake pipe 24, enabling the water to be reused. The dust remaining inside the drain pipe 33 forms lumps under the extrusion of the auger rod 36 and is input into the interior of the collection cover 34 as the auger rod 36 rotates. The collection cover 34 collects the dust. By removing the collection cover 34, the dust can be cleaned, improving the cleaning effect of the dust.

Matters not covered by the present invention belong to the common general knowledge of those skilled in the art.
